"Mirror, Mirror" star Lilly Collins says new Snow White can take care of herself

Lilly Colllins as Snow White.

Once upon a time, Snow White was a fairy tale about a young beauty saved from evil by a handsome prince.

In 2012, Ms. White takes a slightly different approach in the highly-anticipated film "Mirror, Mirror."

“We put a new twist on it where the girl ends up saving the boy as much as the boy ends up saving the girl in the end,” star Lilly Collins, 23, daughter of rock legend Phil Collins, told FOX411’s Pop Tarts column at the movie’s Hollywood premiere. “It's all about a young woman who finds herself within a story, and learns to believe in herself and love herself from an animated character we originally knew. It's just a really strong story about a young girl who finds herself, and I think everyone can relate to that in some way.”

Collins also shared a special message for young girls who watch the film.

“(Girls) can do as much as boys can. They can save the prince just as much as he can save you," she said. "It's not about the physical beauty that counts, it is what is inside that should propel you forward and knowing that have the ability to do whatever you put your mind too."

Speaking of image, Collins noted that the whole concept of watching yourself on the big screen can be a far more daunting reflection than asking a mirror who is the fairest of them all.

“It's still really weird just seeing the posters. But I am so proud of this movie,  I just love the message of it, so when I see myself I just see all the experiences we had on set, so I am almost just seeing my life on screen not a movie,” she explained. “It depends picture to picture what I feel when I watch myself, and it's a little weird. It isn't normal; there is nothing normal about looking at yourself on a big screen. But you learn to become more comfortable with it.”

And hey, when you’re watching yourself kick the butt of your 6' 5" male co-star Armie Hammer, that helps.

“Armie and I were training for about four months, sword fighting and fencing, wrestling and martial arts. It was all these crazy things that we never thought we would be able to do,” Collins added. “A lot of bruises, I was pretty black and blue, but it was all good because I knew I was working hard.”
